Lithium Battery Capacity Indicator Module
This tiny lithium battery level indicator board contains a five-level LED indication to show how much power is left in the battery. With the help of this level tester, you can keep an eye on the charge and discharge levels of your battery. 5 Level LEDs illuminate, as can be seen below, at a specific battery voltage level.

How to Set 7V DC to 13V DC Volt Batteries
First Battery Fully Discharged
Connect the module to the battery output with proper polarity
And adjust the variable resistor to set all led’s off
Charge the Battery & 5-LEDs glow up at a specific voltage level of the battery.
